The average lifespan of a Dachshund is around 12-16 years. However, this lifespan can vary depending on several factors such as genetics, diet, and overall health.

Dachshunds are prone to certain health issues such as intervertebral disk disease, obesity, and respiratory problems. Regular veterinary check-ups, a balanced diet, and exercise can help prevent or manage these conditions and increase their lifespan.

Additionally, genetics play a significant role in determining a Dachshund’s lifespan. Purebred Dachshunds have a higher risk of certain health problems, but they also have more predictable lifespans compared to mixed-breed dogs.

It is important to note that proper care and attention to their health can greatly impact a Dachshund’s lifespan. Feeding them a well-balanced diet, providing regular exercise, and avoiding obesity can all contribute to a longer lifespan. Regular visits to the vet for check-ups and preventive care can also help detect and treat any health issues early on.

Furthermore, providing a safe and secure living environment, along with adequate mental and physical stimulation, can also enhance their overall well-being and lifespan.

In conclusion, the average lifespan of a Dachshund is 12-16 years, but this can vary depending on factors such as genetics, diet, and overall health. Providing proper care, attention to their health, and a safe and stimulating environment can help increase their lifespan.
